FURNITURE CONSTRUCTION.

Specification of Letters Patent. t t t 14, 1920 Application an December18,1315. Serial No. 67,498.

To all whom it may concern Be it known that I, JOHN F. GAIL, a citi-.

Construction, of wiich the following isaspecification. V V I Thisinvention relates to improvements'm furniture construction andmoreparticularly to a new and improved means for connecting theuprights, cross-rods, tubes, bars or other like members of a furnitureconstruction to the side wall of a post frame, cross-rod or other memberpositioned transversely of the first mentioned member. More generallythe invention refers to means for holding in fixed position the end of across connecting member in proper relation to the side wall of a framemember.

T he salient objects of the invention are to provide newand improvedmeans for fastening together the various component parts of a furnitureconstruction such as form the a cap or ferrule normally used to fit overand conceal the end of a cross connecting member is used also as thesecuring means, being preferably welded to the side wall of the framemember; to provide a construction in which the cap or ferrule whichforms the combined finishing piece and holding member is in the form ofa cap substantially closed at one end, there being, however, an aperturein the end of the cap forming an inner ring portion which is welded orotherwise secured to the side wall; to provide a construction in whichthe side wall of the bar to which the cap is secured is preferablyprovided with an aperture registering with the aperture in the cap sothat the two elements have corresponding inner rim or ring portionswhich can be welded together; to provide a constructi n in which thecaps or ferrules previously mentioned are secured to the side wall ofthe frame member or cross conne: ting piece by joining them throughwelding or otherwise integrally connecting them in a circle or otherrelatively large area; to provide a construction in which where theframe members are constructed of relatively light lock-seam tubing, theconncction between the ferrule and the tube can be advantageously madeat the lock-seam joint; to provide a construction in which the securingmeans is so arranged that the sides of the apertured portions ofthe'lo-Ikseam joint can be welded or otherwise caused to become unitary,thus strengthening the lock-seam joint and more securely fastening ittogether; to provide a construction fastening the filler bars or thelike to the v posts, cross rails or other frame members; to provide aconstruction which can be economically manufactured and shipped owing tothe fact that a maximum amount of strength can be obtained with aminimum amountof material; to provide a c0nstruction in which the jointsof the finished articles willbe entirely concealed within the finishingpieces, which latter can be economically formed of stampings; and ingeneral to provide a simple and improved construction of the generalcharacter referred to. i Y

In the drawings: v

Figure 1 is a front elevation, parts being broken away and shown insection, of a bed unit embodying my invention,

Fig. 2 is an enlarged fragmentary top plan viewof the lower cross railshowing the ferrule in place with the filler bar removed.

. Fig. 8 is an enlarged fragmentary cross section View, through theparts shown in Fig. 2.

Describing in detail the particular embodiment of my invention shown inthe drawings, 1 designates the top rail of a head or foot unit of a bedand 2 and 3 the side posts thereof. The top rail and side posts arepreferably formed integral from a continuous length of lock-seam tubing,the lock-seam 4 thereof being positioned on the interior side wall ofthe posts when the latter are bent down into substantial parallelism asshown in Fig. 1. The posts are supported at. their lower ends by theusual ner hereinafter described in detail. A similar series of ferrulesor caps 12 are secured to the lower wall or surface of the top rail 1and these opposed ferrules are adapted to receive a plurality ofuprights or filler bars 18.

The present invention contemplates that the caps or ferrules which serveas the finishing pieces shall comprise the sole securing means forholding the uprights in fixed relation to the top and bottom rails andthe latter in fixed relation to the side posts. The construction andmanner of securing these caps or ferrules forms an important feature ofmy invention and is shown in detail in the enlarged fragmentary views ofFigs. 2 and 3, the connection only between one'of the ferrules and thebottom rail 7 being described in detail, since the remaining connectionsare of the same type.

Extending through the lock seam 10 is an aperture 14: which provides aninner rim or edge 15 through the lock seam joint. This rim or edgeregisters with a similar rim or edge 16 surrounding the aperture 17formed in the closed ends 18 of the ferrule. In attaching the latter tothe cross rail the cap or ferrule is positioned so that its apertureregisters with the corresponding aperture in the lock seam of the crossrail and the inner rims or edges welded or otherwise integrally unitedto form a unitary structure. This novel construction not only permits avery rigid and eflicient connection between the cap and the cross railbut it can also be used for more securely fastening together theinterlocking portions of the lock seam joint, thusstrengthening thecross rail at the points of connection between the latter and theferrules.

' ting connection.

In assembling the bed unit, the stock for the main frame is bent to formthe top rail and side posts, the ferrules are secured to the side postsand the bottom and top rails, and the ends of the bottom rail and fillertubes pressed or otherwise inserted in their respective ferrules so asto form a tight fit- While the ferrules may be secured to the side wallsof the respective rails or posts by any known system of welding or thelike, I have in the particular embodiment of my invention, shown in thedrawings, secured them together by acetylene welding, causing the flameto pass down through the aperture 16 against the side walls surroundingthe registering apertures of the ferrule and cross rail, thus causing ahomogeneous inner wall to be produced surrounding the apertures in thetwo elements. lvloreover, this manner of securing the parts togetherproduces a fusing of the metals in a ring or at spaced points, thusgiving a greater strength that where a single spot is welded in thecenter. In its broader aspects the invention is not limited to theparticular form or area of connection shown nor in any manner except asspecified in the appended claim.

I claim as my invention:

In furniture construction, the combination of a pair of initiallyseparate parts, comprising a tube and an end socket for a spindle havingan end wall butted against the Wall of the tube, said walls having acommon opening therethrough surrounded by a connecting ring consistingof a consolidated composition of the metal of both Walls.
